Transformers, utilizing advanced production equipment, adopt a new process of coil epoxy vacuum casting and CD type iron core. Compared with similar oil immersed transformers, they significantly reduce weight and volume, improve insulation strength and moisture resistance in terms of quality, and effectively weaken leakage magnetic flux, greatly enhancing the transformer's ability to withstand the impact of test short-circuit currents.

The product has the characteristics of light weight, small size, beautiful appearance, stable performance, and easy to use and carry. It is particularly suitable for on-site operation and is a new type of AC/DC dual-purpose high-voltage test transformer that has been updated and replaced in China. This series of products is suitable for on-site testing of insulation performance of various electrical equipment in power systems and various power users, as well as high-voltage power sources in various voltage systems or devices with DC high voltage and low current of electrical products.
